So playing unbirth with the console cheat/compatibility mode I can get through fine...but then I got to the living room and found a bright pink sofa. I fixed it and a number of other unfitting textures that were unfinished or out of place. There are 13 of them (you can go ahead and skip floor 4 but I recommend the others). These are quick fixes (a couple of minutes apiece), but they look alright in the game. All you have to do is copy the new files over the old ones (you can tell where to look from the file name) in the texture area.

Oh, and the toilet just happens to work well enough to be totally gross--look inside when you see it. I might post screens later.
